HP's first convertible Android tablet, the SlateBook X2 is now available on
the company's US website.

HP has quietly started selling its SlateBook X2 convertible tablet online in the United States, featuring a detachable keyboard and Android 4.2 (Jelly Bean).

First announced in May, the Slatebook X2 has a 1.8 GHz quad-core Tegra 4 processor, 2 GB of RAM, 16 GB of internal storage and a 10.1-inch 1920 × 1200 touchscreen display.

Despite running Android, it is intended as both an entertainment and a work device. The detachable keyboard contains a second battery which allows users to keep working for longer, and they can also print directly from most applications.

The SlateBook x2 is available from the company's US website at a price of $480. An HP spokesperson confirmed to the Telegraph that the device will also be launching in the UK at the end of August, at a price of £379.

The SlateBook X2 is HP's second Android-based device, following the launch of the £139 Slate 7 tablet in May. The company also offers another convertible device – the Envy X2 – which has an 11.6-inch screen and runs Windows 8.

It will go head-to-head with Asus’ Transformer range of convertible devices, which also runs Android. However, it is substantially cheaper than Asus' flagship Transformer Pad Infinity, which launched last year at a price of £600.
